The note, when evoked in perfumery, presents itself as a remarkably delicate and airy impression, often interpreted as a whisper of spring. It is soft, subtly powdery, with a tender, clean muskiness that feels almost tactile, like the silken fuzz of the catkins themselves. There's a nascent greenness to it, not sharp or herbaceous, but rather the pale, almost translucent green of new life emerging. It possesses a faint, ethereal sweetness, akin to pollen caught on a gentle breeze, rather than a sugary or overtly floral bloom. Its intensity is inherently mild, projecting softly and intimately, typically settling as a heart note that bridges a fresh opening to a gentle, clean drydown. Its longevity is moderate, lingering as a soft, comforting aura.
